Is there a way not to optimize out "static const" at -Os?

[David Kang <dkang@xxxxxxx>]

 Hi, 
I want to let the gcc leave the following static const at the optimization -Os.
The functions "A_exec0", "A_initialize" are static function.
I tried a few compiler options such as "-fkeep-static-consts".
But gcc optimizes it out at -Os.
My compiler is gcc-4.7.3.
"-fkeep-static-functions" doesn't seem to be supported by my compiler.

static const __attribute__((unused, section(".driver_table"))) driver_t driver = {    
  .type = "A_driver",                                                       
  .initialize = A_initialize,                           
  .executors = {A_exec0 }               
};

 Any idea about how to keep the static const and keep the section ".driver_table"?

 Thanks,
 David
